Of the 3 programs you attached me I was seeing Unwarp 3D but I can't understand how it works.

In practice, as I understand, you have to insert a geometry drawn in MOI and exported to Obj for example and he creates a flat square image where you then create the texture with a photo editing program? .... or does it work differently?

Yes, Artlantis Studio is a program that they use a lot in architectural rendering but I'm trying to make it work even for not too complex objects.
